Patent ES-464935-A1 (ES)
Title: Drive assembly
IPC: F16H3/54
Filed: 1977-12-09
Abstract: A drive assembly includes a casing containing a planetary gear assembly. A speed control arrangement is provided in association with the planetary gear assembly to vary the speed of rotation of an output member relative to the speed of rotation of an input member. The speed control arrangement includes a first disc pack which is engaged under the influence of a spring to prevent relative rotation between a ring gear and a planet carrier. A second disc pack is also engageable under the influence of a spring to prevent rotation of the ring gear relative to the casing. Hydraulic motors are selectively operable to release the disc packs against the influence of the associated springs. In the event of a failure in the source of hydraulic fluid, both disc packs are engaged with a resulting braking of rotation of the driven wheel. A secondary or towing clutch is selectively disengageable to release the output member and wheel for rotation, even though both of the disc packs are engaged. The springs cooperate with the disc packs in such a manner that wear is minimized. Compact construction of the drive assembly is promoted by eliminating the use of bearings to hold the ring gear against sidewise movement. The compact construction of the drive assembly is also promoted by forming the ring gear with a pair of annular side sections which have the same inside diameter and which extend axially outwardly from opposite sides of the ring gear into engagement with disc packs.

Title: Process and a circuit arrangement for the control of the primary current in coil ignition systems of motor vehicles
IPC: F02P3/05
Filed: 1978-10-24
Abstract: The current through the primary winding of an ignition coil of an ignition system for a motor vehicle, and being largely independent of engine speed, supply voltage and internal resistance of the ignition coil, is controlled in a circuit in which a capacitor is charged only during the open time of a breaker contact and is discharged during the closed time of the contact, whereby the relationship of the charging current to the discharging current is equal to the relationship of open time to closed time of the contact. The current is switched on through the primary winding of the ignition coil as soon as the capacitor voltage falls below a threshold value and the current through the ignition coil is limited to an optimum value. The flow of current through the ignition coil is interrupted when the breaker contact is open and the aforementioned threshold voltage has not been reached at the same time.
